Usage

Stream some data from some server:

import React, {useCallback, useState} from 'react';
import {useStream} from 'react-fetch-streams';
 
const MyComponent = props => {
    const [data, setData] = useState({});
    const onNext = useCallback(async res => {
        const data = await res.json();
        setData(data);
    }, [setData]);
    useStream('http://myserver.io/stream', {onNext});
 
    return (
        <React.Fragment>
            {data.myProp}
        </React.Fragment>
    );
};

You can also pass the fetch request init props using fetchParams:

import React, {useCallback, useState} from 'react';
import {useStream} from 'react-fetch-streams';
 
const fetchParams = {mode: 'cors'}
 
const MyComponent = props => {
    const [data, setData] = useState({});
    const onNext = useCallback(async res => {
        const data = await res.json();
        setData(data);
    }, [setData]);
    useStream('http://myserver.io/stream', {onNext, fetchParams});
 
    return (
        <React.Fragment>
            {data.myProp}
        </React.Fragment>
    );
};
